These were both new to me, and I doubt they may have been published, although both works were performed in New York during 1950s. Would expect these must be held either by a library in the NY area (I checked a couple but no luck), or alternatively, not sure if there is a Templeton archive somewhere in the USA since Templeton lived and died in the USA in the 2nd half of his life ?

Here's a link to a biography of Dublin-born composer Archy Rosenthal,
together with his Etude for Piano. This score has interesting provenance,
as the front cover has an inscription 'Bonnie Shasband(?) - from her friend
Archy Rosenthal'.
